中文摘要：
以吐鲁番长焰煤及其热解半焦为原料,经筛选采用AB复合黏结剂压制型煤,利用X射线衍射和扫描电镜研究型煤的成型机理.结果表明,AB复合黏结剂的最佳配比为：添加量11%,组分A和B质量比为5∶3,相应型煤具有较高的强度和良好的防水性;黏结剂加入煤中形成水化相C,其稳定存在且均匀分布在煤粒间并与煤粒紧密结合使型煤具有较高强度,半焦型煤中C水化相更多且与半焦颗粒结合更紧密,致使半焦型煤强度高于长焰煤型煤强度.
英文摘要：
Long flame coal and its pyrolysis blue-coke are used to prepare briquettes based on several kinds of binders,and the forming mechanism of briquettes was studied by XRD and SEM.The results showed that the best optimum formula for AB composite binder is following：while the added amount is 11% and the mass ratio of A and B is 5∶3,corresponding briquette has high strength and waterproofing.The composite binder convert into hydration phase C,which can stably existence and closely combine with the coal or blue-coke particles and further make briquette possess higher strength.Moreover,there are more C and better combination between C and those particles in the blue-coke briquette than long flame briquette,which result in the higher strength of the former than the latter.
